============================================================================
DSP Production Firmware Version 1.3 release notes:

- This is the user loadable version of the Factory 1.3 DSP firmware.  
  Will display as "DSP App Ver:U1.3" after loading and is identical to the
  factory "F1.3" load.

- Please use with CPU version 1.2 or higher, otherwise some features
  may not operate properly

- On P25 9600bps Control Channels, will dump multi-packets to the PC/IF port
  while CCDump is enabled.  This is to add further support for 3rd party 
  trunking analysis PC software for P25 systems.

  This [new feature] will have slightly increased reliability when used with 
  CPU version 1.4 firmware or above.

  Otherwise this version is identical to DSP version 1.2.  Everyone can upgrade
  to version 1.3 even if external trunking analysis software is never used.
